General Laser Safety Guidelines

When working around ports that support optical transceivers, observe the following safety guidelines to
prevent eye injury:
Do not look into unterminated ports or at fibers that connect to unknown sources.
Do not examine unterminated optical ports with optical instruments.
Avoid direct exposure to the beam.
WARNING:
The lens in the human eye focuses all the laser power on the retina, so focusing
the eye directly on a laser source—even a low-power laser—could permanently
damage the eye.
Unterminated optical connectors can emit invisible laser radiation.
